what i mean is
2nd hand types
like the recent influx of Q9000 series of Core 2 extreme

for me the difference between i7 920 to even 965 is minimal at normal usage

the 970 980x is different
cant underestimate the extra 2 core in the future

How is that a bad thing? IB still has better performance/watt compared to SB.
I've mentioned already in the past that there will not be a 4GHz IB even if it possible to do so. The sub 4GHz frequency is due to the fact that more performance is not IB's aim. Intel's aim is to have better performance/watt and better IGP, both of which benefits the mobile end and has very little significance to the desktop end. It is rumored that most IB should be able to go 5GHz. This is 500MHz more than the 4.5GHz that majority of users will be able to attain easily with SB. If Intel were to increase the base frequency, then it will not look as though it has better overclocking headroom compared to SB.

Things could also go backwards with overclocking potential decreased with a shrinking manufacturing process but that is not 100% confirmed. With Intel increasing their maximum 57x multiplier on SB to 63x multiplier on IB, it is possible to assume that a huge majority of IB chips will be able to overclock till 5GHz.

77W TDP is great cause power efficient so we can pay lesser money for TNB Better IGP? Will it run some online games smoothly?

say..the IB suppose to have 20% more performance than the SB..does the extra 20% means the IGP? or the total performance...coz from the benchmark..it seems the difference is low ..less than 5 %..(rough idea..lazy to count)..

not bad from expectation i hope that spring will pass quickly 
aim for 3770K 

Just curious, im using i7 930, just recently oc to 3.8ghz.
I have never max out or hit 80% of cpu usage, even when playing some games, with couple of background process..

Is cpu already too fast for current software?

Expect a 10-15% performance improvement overall, clock-for-clock in comparison of the 3570k and the 2500k.
Honestly, I don't think it'll be worth for Sandy Bridge users to upgrade.

Ivy Bridge biggest change is a better intergrated GPU (expecting it to rival AMD Llano), a faster Quick Sync and a cooler/lower power consumption CPU.

Yeap, you'll get better OCing potential out of IB.
But IB are meant to be drop-in replacements for SB, so I still don't think it'll be feasible for an upgrade. 2500k at 4.5ghz is still plenty fast for most programs today and atleast the next 2 years.
On a related note though, Intel phail.

Since when IB got 2mb cache ? except for i7-3770K?

Right now , if I remember correctly , when i5 2500k was release the price would be around RM 700-710 right ?
2500k = USD $216 , 3570k = USD $225K
Guess need to save up how much ? with our malaysia currency rate with USD 3.185 ?

Well with potential extra 500MHz OC, and a HT then another 2 MB extra cache, I think I will upgrade. And my Mobo is 5years warranty. that means if I take care it might last at least 7years. So I think I will benefit much on Ivy after 4-5years.

Overclocking with SB is easier than ever before. You don't OC the idle state, you only OC the turbo. Normally a SB 2500k idles at 1.6 GHz and goes up to 3.3-3.7 GHz when it gets something to do. If you change the multiplier to 40, it means the turbo has been overclocked and the processor will run at 4.0 GHz (or slightly lower, depending on how you adjust the settings in the BIOS) under load. Idle will remain at 1.6 GHz regardless, unless you completely disable the Turbo function.
